A Versatile Impactor-Inspired Sample Chamber with a Virtual Pin-Grid Array for Sensor Performance Evaluation

Abstract

An impactor-inspired sample chamber was constructed and assembled to evaluate sensor performance during exposure to trace analytes, such as explosives and chemical warfare agents. A flexible, virtual pin-grid array (PGA) was created with a series of hardware and software to make electrical connections without need to create prototype, expensive circuits. The sample chamber and Virtual-PGA electronics were characterized and tested using a thermal imager and a custom temperature and relative humidity sensor. The chamber and electronics are capable of evaluating sensor performance under a variety of environmental conditions and analytes.
